Q2. For some types of plants, when plants with different colored flowers are crossbred, one color does not dominate over the other. Instead, the offspring have flowers that are a blend of the colors of the 2 parent plants. Mendel found that when he crossed a snapdragon with red flowers with a snapdragon with white flowers, the resulting offspring had pink flowers. In other words, when a red snapdragon of type RR was crossbred with a white one of type WW, the resulting offspring of type RW had pink flowers. Suppose a white snapdragon is crossbred with a pink snapdragon. What is the probability that a resulting offspring will be:

a. Red?
b. White?
c. Pink?
